This invention, relates to roller bearings and has for its object to produce a simple, economical and efficient bear ng in'whichthe rollers will be held against lateral twisting 5 and in and out movement to insure retention of operative position and relation. A further object is to provide agroller cage making provision'for a'thorough and uniformdistribution of the lubricant to the rollerspa A still further object is to produce a. cage composed of concentric members havinglugs whereby spacing apart at equal distances of the membersis accomplished and relative longitudinal movement of the members-is inhibited. I I I With these general objects in view, the invention consists/in certain novel and usefulfeatures of construction and combina tions of parts as hereinafter describedand claimed, and in order thatit may belfully understood, reference is to be had to thoraccompanying drawing, in whichz-r I Figure 1 shows a tapered rollerb'earingr as viewed from its larger end, one-half of the bearing appearing'in central cross section.

' Figure 2 is a longitudinal section taken on the line II-II of Figure 1. I r V Figure 3 is a sectionon-the line III-III ofFigure1.

' Figure tis an end view of therollers and the carrying cage therefor, the inner ring! member of the latter beingv disclosed as. of different-shape and lesser size/than it appears when complete and in final =oper-ative-position. 7

In the said'drawing, 1 indicatesthe inner cone and 2 the outer cone of a roller bear ing for automobiles and; the like, the opposing faces'of the cones which arearranged concentric-ally,vbearing a taperedrelation I The cage of the bearing essentially-com prises concentrically disposed ring members 3 31 6114. In the preferred typeof'eonstruction, there is a third ring member 5, interposed between theouter member 3'and the inner member 4%, and'said members, for the accommod ation or'reception of a series of equispaced rollers 6, are providedwith openings 7, 8 and 9, the openings 7 and 8 being narrower than the diameter ofthe rollers so that the latter shall-be incapable of inward or outward displacement whenonce assembled in operativere'lation to the cage, The width of each opening 9 corresponds substantially to the diameter of the respective roller, and to space the member 5 centrally between the members 8 and 4t, suitablelugs are provided, there bemg lugs PI'OJGClJIIlg from the member 5 both inwardly and outwardly, lugs projecting outwardly fromthe inner menr ber, and lugs projecting inwardly from'the outer member. 'All of the-lugs cooperate in accomplishing .lthe spacing 1result-men tioned! There are alsolugs to guard against relative longitudinal slidable n'iovement of the ineinbers which might result in their slippage or separationbefore therollersare disposed-1n operative position. When the rollers are in operativegposition: no such slidable separable movement can occur because'each rolleris occupying one set of radially alincd openings 7, 8 and 9, but it is preferred to depend on the proper lugs for this result so to avoid end friction on'the rollersm To fitor nest the ringmembersin operative relation, 't'heyJmustfirst he slipped one within the, other with the said radial openings out of alinement, and then relatively rotated to ln'ing'saidopenings into radial alineinentj This action 1 its-necessary .because the lugs mentioned. it initially in longitudinal alinement, would prevent the ring members being nested together. They are therefore nested with thesaid lugs'out ofali'nement,

andarethen rotated properly tobring the said openings intoyregister and incidcntally bring :the lugs in longitudinal 'alin'ement. as indicated at the lower. side of, Figure 2, and: Yin! "Figure reter- 'ence to the latter figure showingthat "it will bewimpossible. for the inner ring -member 'toslide to the left onthe ring member 5,101 the outer member 3-to slide to the right gardless of the presence or absence of-the rollers dcas it'is a preferred construction to I prevent longitudinal,- sliding rnoveinents of the rings which might bring them into trim time c s nt with'both ends "of the ion on tlie ring member 5, and this is true rein radial planes between the rollers, and those which serven'ierely for the spacing of the rings 5, are best shown in Figures 2 and 3, those on rings 3 and 4 being respectively identified by number-s10, 11 and 12.

The lugs depended upon to preventthe relative sliding movement of the rings are marginal lugs and are alsobest shown in Figures 2 and 3, those on rings 3 and 4, being longitudinally alined with andsimilar to lugs and 12, and being numbered 13 and 1 1 respectively. On the ring fn'there are outwardly projecting marginal lugs 15 engaging the outer side of certain ofthe marginallugs 13 of-ring 3, and inwardly projecting marginal lugs 16 engaging the opposite side of certain of the lugs let-of ring' l, when the rings are adjusted rotatably to bring theiropenings inregistenand it will benotedby reference particularly to- Figures 1, 2 and 3,'that lubricant can bepacked and flow as'freely in the spaces between the rings asbetweerrthe latter and the bearing cones 1,-and2'. g i

To provide for placing the rollers inoperative positiomthe inner ring 4-, is initially made with the parts for disposition atthe :en'dsof the rollers, pressed inwardly in concave fornras at 17, thus reducing the size of the ringas a whole, so that it can'be nested within the ring 5 and the circular series of rollers. The rollers are first positioned in the openings of rings 3 and 5 from within the "latter, vand after this is accomplished and the inner ring of reduced size as stated, -is:a.r'ranged as shown by'Figure t, the entire assemblyis placed in a suitable lathe or other tool and the concaved parts '17 are pressed outward until the entirering 4 is -expanded=and concentric with'the otherrings, the

relative straightening of the parts 17 being depended upon to expand the diameter of -ringi l to the relative size indicated iii-Figure ;1.

spectively, near its side margins. The outer ring-'5 has sets of inwardly-projecting marg1nal2lugs-20, to interlock with outwardlyprojecting lugs 18, of ring 5. The inner r ng 4, has-sets of inwardly-projecting mar =g1nal lugs 21 to interlock with inwardly-projecting lugs 19 of ring'5. 'It' will be understood that 1HFlgu105 one ortwo only ofthe sets of lugs 18, 19, 20 and 21 appear.

;In Figure 6 a second modification is shown.

The inner ring 4 has lugs 22 similar to lugs 21 but longer, andtheouterring 3 fits be- .tween-themarginal lugs'22. The intermediate ring 5 has marginal lugs. 23 engaging both rings 3 and 4e, andthe rings 4' and 5, arealso provided with intermediate spacing lugs 24, 25 and 26. Preliminary to assemblage, the lugs 23 at one end, must stand as indicatedin dotted. lines, and are bent outward to operative position to inhibit endwise slippage of the rings. In this case,

and'alsoin the construction shown by Figat any point, but the inner one would-have to be expanded to operative position, as already explained with respect to Figurei. From the above description, it will heapparent-that-I have produced a device of the character described which possesses all of the features of advantage pointed out as desi-rable', and while I have described and claimed the preferred embodiment of the same,'I reserve the right to make all changes of the appended claims.
